ABSTRACT:
A linear guide provides a guide rail, rolling elements, a slider, and a seal device secured to the slider to close the gap between the inner surface of the slider and the outer surface of the guide rail, the seal device has a seal lip which is made of a rubber or synthetic resin, containing the lubricant. When the slider is mounted on the guide rail, the seal lip contacts with the outer surface of the guide rail to close the gap between the inner surface of the slider and the outer surface of the guide rail. The lubricant contained in the seal lip gradually oozes out to the drag surfaces of the linear guide.
